State Water Efficiency & Enhancement Program (SWEEP)

The State Water Efficiency and Enhancement Program (SWEEP) provides financial assistance to growers for on-farm irrigation system improvements that both reduce GHG emissions and save water. It is administered by the California Department of Food and Agriculture (CDFA).

Program Summary

Year launched: 2014
Budget for FY 2019-20: Program funding was cut for this year
Grants awarded to date: $80 million
Total projects funded: 832
CDFA estimated water savings (annually): 35.8 billion gallons (over 50,000 Olympic swimming pools)
CDFA estimated greenhouse gas reductions (annually): 79,987 metric tons CO2, or the equivalent of removing almost 16,000 cars off the road for one year
Status of grant rounds: Seven rounds completed (most recent grant cycle was awarded in Spring 2020).

Program History

In 2014, under an emergency drought declaration, Governor Brown authorized a new program called the State Water Efficiency and Enhancement Program (SWEEP). Funding for the program has come from the state’s Greenhouse Gas Reduction Fund, raised from cap-and-trade allowance revenue, as well as Propositions 1 and 68.

Eligible projects currently include:

  • Weather, soil or plant based sensors for irrigation scheduling
  • Micro-irrigation or drip systems
  • Conversion of a fossil fuel pumps to solar, wind, electric, or natural gas
  • Improved energy efficiency (e.g., retrofitting or replacing pumps)
  • Low pressure irrigation systems
  • Variable frequency drives to reduce energy use and match pump flow to load requirements.
  • Reduced pumping (e.g., improved irrigation scheduling)
  • Other management practices that save water and reduce GHG emissions (e.g., soil management practices such as cover cropping and compost addition that increase water-holding capacity)
